IoT-Based Smart Lock Device Development

@tshibsamuel477

Hi there, I’ve read your specification and can deliver a compact, robust IoT smart-lock prototype meeting all points: GPS/LTE location, accel/gyro/vibration sensing, live audio streaming, precise door-position sensing, capacitive touch lock control with motor + limit switches, OLED status, SD offline logging and Blynk cloud integration — plus 24-hour battery + charging, tamper detection and secure data upload. As a mechanical engineer specialized in mechatronics with ~5 years’ experience in embedded systems and PCB design, I’ve worked directly with GPS/LTE modules, IMUs, microphones, SD storage, power management, motor control and IoT integrations (Blynk/MQTT/REST), and I’m comfortable delivering firmware, hardware and documentation. I’ll produce a working prototype, tested firmware with cloud sync and full docs — message me and I’ll share a short plan, milestones and quote so we can start. Best regard Samuel tshibangu

Hi, I am a PCB designer and embedded systems engineer with 3+ years of experience delivering IoT and automation products from concept to prototype. Your Smart Lock Device requirements align closely with my background in ESP32/STM32 systems, LTE/GPS modules, and multi-sensor integration. I have designed PCBs and firmware that combine motion/vibration sensing, capacitive touch, motor drivers with limit switches, tamper detection, and SD card logging, all while ensuring power efficiency with battery backup and fast charging. My work also includes Blynk IoT and MQTT integration for remote monitoring and control. Key strengths I bring to this project: Strong focus on low-power design, power management, and DFM/DFT best practices. Experience with real-time data logging, GPS/LTE connectivity, and OLED user interfaces. I can provide a production-ready prototype with full documentation and a clear upgrade path for scaling. Best regards, Muhammad Suleman PCB Designer | Embedded Systems Engineer
